Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, a storage case 1 according to the present invention includes a holding plate 2 and a cover body 3.
They are connected to each other via hinge portions 2a, 3a provided at one end side so as to be swingable and openable.
By the cover 2 and the cover 3, a storage state that covers both sides of the recording medium disk 100 can be achieved. The holding plate 2 and the cover 3 are each formed of a transparent resin, an opaque resin, or the like.

The holding plate 2 is provided with a holding portion 5 that fits into the center hole 101 of the disk 100 at substantially the center of the plate surface. Further, the holding plate 2 has a central mounting portion 6 which is raised in a ring shape surrounding the holding portion 5 and a ring-shaped raised outer mounting portion 7 which surrounds the outside of the central mounting portion 6. Are provided. These central and peripheral mounting parts 6,
As shown in FIG. 3, reference numeral 7 denotes a recording area (not shown in FIG.
0 is a doughnut-shaped area excluding the vicinity of the center and the periphery).

The height of each of the mounting portions 6 and 7 is 1 mm.
The following is sufficient. In this embodiment, the thickness is about 0.7 mm. As shown in FIGS. 3 to 6, the holding portion 5 includes a base 10 extending from an inner peripheral surface of a hole 9 provided in a central portion of the holding plate 2, and a circumferentially extending from the base 10. Enlarging part 12
And a projection 13 protruding radially outward from an end of the enlarged portion 12. The diameter of the enveloping circle at the tip of the projection 13 is made larger than the diameter of the central hole 101 of the disk 100, and the outer diameter of the enlarged portion 12 is large enough to fit in the central hole 101 of the disk 100. Have been.

That is, the position of the projection 13 is provided so as to be displaced in the circumferential direction from the position of the base 10. More specifically, the base 10 is formed from the inner peripheral surface of the hole 9 of the holding plate 2,
It is provided in a radially inward direction and is inclined upward in the axial direction, and
A plurality is provided at predetermined intervals in the circumferential direction. The enlarged portion 12 extends coaxially in one circumferential direction through a rising portion 11 that rises in the axial direction from the inner end of the base portion 10. At the end of the enlarged portion 12, a pushing portion 14 extending in a radially inward direction is provided. The protrusion 13 is provided at an upper end of the end of the enlarged portion 12.

A hole 9 provided at the center of the holding plate 2
Substantially coincides with the inner peripheral portion of the central mounting portion 6. The pushing portions 14 are separated from each other by a dividing portion 15 and can be operated independently. Bases adjacent to each other in the circumferential direction
A dustproof piece 16 is provided between the base 10 and the base 10. That is, the dust-proof piece 16 is separated from the inner peripheral surface of the hole 9 by the base portion.
It is integrally formed with the same inclination as that of 10. The circumferential end of the dust-proofing piece 16 is separated from the base 10 via a radial notch 17, and the radial inner end of the dust-proofing piece 16 has a circumferential notch.
It is separated from the enlargement section 12 via 18.

The dust-preventing pieces 16 prevent dust from entering the holding portion 5. In addition, the dust that has entered is protected by the central mounting portion 6 from reaching the recording surface 102 of the disk 100. In this embodiment, the base
Reference numeral 10 is arranged at three equally-spaced positions in the circumferential direction. Accordingly, the protrusion 13 and the pushing portion 14 are also arranged at three positions in the circumferential direction, which are positions shifted from the base 10 in the circumferential direction. The amount of movement of the pushing portion 14 in the axial direction (the thickness direction of the holding plate) is about 2
It can be moved very large, on the order of mm. Even if the pushing portion 14 is pushed so large, the expanding portion 12 and the base 10 can be elastically deformed without being damaged.

When this type of case is made of only a transparent PS resin in which no high-impact PS resin is mixed, there is a limit to imparting a spring property due to the characteristic of the PS resin that it is easily broken. Although the function of taking out a disk such as a CD or DVD with a single touch was not practically effective in providing a spring property, the shape of the central holding portion 5 as shown in the storage case having the above structure was adopted. It solved it and made it possible. That is, the base 10
As shown in FIG. 6, the holding plate moves inward in the radial direction.
2 has a slope that is higher than the plate surface, and this slope serves as a bending allowance.

Therefore, when the holding portion 5 is pushed in as shown in FIG. 9, a pressing force is applied to the pushing portion 14, so that the rising portion 11 is inclined inward in the radial direction, and the expanding portion is enlarged. 12 and the base 10 are bent. As a result, as a whole, the holding portion 5 has a sinking action and a diameter reducing action. Note that, since the sinking action and the diameter reducing action occur while resisting the elastic restoring force, if the pushing operation of the pushing part 14 is stopped, the holding part 5 naturally rises to eliminate the sinking. In addition, enlargement is performed to eliminate the diameter reduction effect.

In the enlarged portion 12 having such a structure, the projection 13 is provided so as to extend radially outward at a portion to be extended, that is, a position to be a root of the pushing portion 14.
The projection 13 normally has a central hole 10 in the disc 100.
1 to interfere with the edge of the opening, that is, hinder the fitting of the central hole 101. That is, each of the protrusions 13
The diameter of the envelope circle at the tip of
One is larger than the diameter. Specifically, for a diameter of 15 mm of the central hole 101 of the disc 100, about 0.2 mm
mm. The outer diameters of the rising portion 11 and the enlarged portion 12 are set to be large enough to fit in the central hole 101 of the disk 100, but in this embodiment, they are slightly smaller than the diameter of the central hole 101 of the disk 100. Diameter. Specifically, it is reduced by about 0.1 mm.

Then, the disc 100 is mounted on the holding portion 5.
In the state where the disk 100 is fitted, the protrusion 13
When the pressing portion 14 is pressed, the protrusion 13 moves to the lower surface side of the disc 100.
The base 10, the enlarged portion 12, and the rising portion 11 are provided so as to be elastically deformable. The disc 100 is attached to the holding portion 5.
It is preferable to set the amount of protrusion of the projection 13 so that a click is generated when the disk 100 is fitted and when the pushing part 14 is pushed to release the fitting of the disk 100.

The upper surface of the projection 13 forms the upper surface of the holder 5, and when the disk 100 is fitted to the holder 5, the distance between the upper surface of the disk 100 and the upper surface of the holder 5 is The thickness is not more than the thickness. In particular,
For a thickness of the disc 100 of 1.2 mm, the disc 100
The distance between the upper surface and the upper surface of the holding section 5 is about 0.5 mm. That is, the thickness of the projection 13 is about 0.5 mm. Further, the distance from the back surface of the holding plate 2 to the upper surface of the holding portion 5 is preferably about 4 mm, and is about 3.8 mm in this embodiment.

The distance between the lower surface of the projection 13 and the upper surface of the central mounting portion 6 is substantially equal to or slightly larger than the thickness of the disk 100. As shown in FIGS. 10 to 12, the holding plate 2 includes a hinge-joining-side edge portion having a hinge portion 2a,
It is formed in a rectangular shape having a free edge opposite to the hinge-joining edge and upper and lower edges opposed to each other via these edges. The holding plate 2 holds the disk 10

As shown in FIG. 13, a slightly protruding rear surface rib 20 is formed on the outer peripheral edge of the rear surface. Side ribs 21 are also formed on the side surfaces of the holding plate 2.

A peripheral wall 22 having a predetermined thickness is formed to project from a peripheral portion of the upper surface of the holding plate 2. On the upper surface of the holding plate, an arc-shaped wall 23 having a predetermined thickness is formed so as to protrude from a portion surrounding the outer peripheral surface of the disk 100. These ribs 20,21
The peripheral wall 22 and the arcuate wall 23 function as a reinforcing member for the holding plate 2 and reduce the thickness of the holding plate 2. The peripheral wall 22 at the upper and lower edges is divided at a central portion by a predetermined distance, and an end of the divided peripheral wall 22 is the arc-shaped wall 23.
It is continuous. The holding plate at the position where the peripheral wall 22 is divided

Are escape portions when the disc 100 is taken out.

An end recess 25 is formed at the upper and lower edges of the holding plate 2 on the free edge side. The peripheral wall 22 at the upper and lower edges of the holding plate 2 is formed as a bent portion having a first step portion 26 slightly entering the upper and lower edges and a second step portion 27 further entering the inside. An engagement recess 28 is formed in the first step 26. As shown in FIGS.
The holding plate 2 is provided with a communication hole 29 that penetrates in the thickness direction and communicates with the engagement recess 28. By providing such a communication hole 29 in the holding plate 2, the holding plate forming die can be a two-part upper and lower mold.

Conventionally, since such a communication hole 29 is not provided, the holding plate molding die is a four-part mold divided into upper and lower parts and left and right parts.
It can be a two-piece type. Further, the central portion of the peripheral wall 22 at the free edge of the holding plate 2 is recessed inward, and this recess serves as a finger locking portion 30 at the time of opening and closing operation. The hinge portion 2a is composed of a hinge piece protruded from upper and lower ends of a hinge connection side edge, and a hinge shaft 31 protruded from an inner surface of the hinge piece opposite to the hinge piece. The hinge piece is formed thick to improve the strength.

17 to 19 show the details of the cover 3. The cover body 3 has a hinge-joining side edge hinged at one end thereof, a free edge opposite to the hinge-joining side edge, and an upper and lower side facing each other via these both ends. It is formed in a rectangular shape having an edge. The upper and lower edges of the hinge connection edge of the cover 3 are

The bearing portion is provided with a hole 35 that pivotally supports the distal end of the hinge shaft 31.
And a notch 36 for supporting a semicircular portion at the base end of the hinge shaft 31 and opening the remaining semicircular portion. The hole 35 is also opened on the surface side of the cover 2. At the center in the vertical direction of the free edge of the cover body 3,
A recess 37 is provided. The recess 37 is provided in the holding plate 2
Corresponds to the finger locking portion 30 of FIG.

On the other hand, at the upper and lower edges of the cover body 3,
A peripheral wall 38 that rises in the thickness direction of the case is provided. As shown in FIG. 18, the height of the peripheral wall 38 is
a and the free edge side 38b are formed high. That is, the central portion 38a and the free edge portion side 38b are fitted into the central concave portion 24 and the end concave portion 25 of the holding plate 2, and the height of the peripheral wall 38 in this portion is set in the storage case. It has a thickness of 1. A knurl 39 is formed on the outer surface of the peripheral wall on the free edge side 38b to prevent slippage when the cover body 3 is opened and closed.

The peripheral wall 38 is provided with an engaging projection 40. Further, adjacent to the engagement protrusion 40, the engagement protrusion 40
A positioning protrusion 41 having a smaller protrusion amount is provided on the peripheral wall 38. When the cover body 3 is closed, the engagement projection 40 is engaged with an engagement recess 28 provided on the holding plate 2 so as to be detachable, and the positioning projection 41 is formed on the holding plate 2. It comes into contact with the inner surface of the peripheral wall 22. 22 to 24 show the details of the engaging projection 40 and the positioning projection 41. FIG.
That is, the cover body 3 is provided with a communication hole 42 that communicates with the engagement protrusion 40 and penetrates in the thickness direction. When the cover 3 is closed, the communication hole 42
The peripheral wall 22 is provided at a position closed by the upper surface of the first step portion 26. Therefore, dust is prevented from entering the inside of the case through the communication hole 42.

As shown in FIGS. 25 and 26, the cover
3 is formed larger than the holding plate 2 so as to completely cover the holding plate 2. That is, the end of the cover body 3 near the hinge portion 3a projects outward from the end of the holding plate 2 near the hinge portion 2a, and the peripheral wall 43 is provided at the protruding portion. . When the storage case 1 is stored in a case rack (not shown) or the like, the peripheral wall 43 can be conveniently used as a finger hook 44 when the storage case 1 is individually pulled out. In addition, a label seal (not shown) or the like may be attached to the inside or outside of the peripheral wall 43 and used as an index.

When the holding plate 2 and the cover 3 are closed by swinging each other at the hinges 2a, 3a, the inner surface of the cover 3 and the upper surface of the holding portion 5 of the holding plate 2 are closed. Is
The gap is in contact with or is smaller than the thickness of the disk 100. Then, the holding plate 2 and the cover 3
It is preferable that the thickness of the case 1 in a state in which both are closed is 6 mm or less. That is, as described above, in the present embodiment, the storage case 1 has the two-piece structure of the holding plate 2 and the cover body 3 and the shape of the holding portion 5 has the shape shown in FIG. In combination, the total thickness can be made extremely thin. That is, most conventional storage cases of this type have a three-sheet configuration including a pair of cover members and a holding plate to be inserted therein, so that the overall thickness is about 10.4 mm. In the case of the present embodiment, it has succeeded in suppressing the width to about 5.2 mm, which is half of that. Also, a currently known two-layer CD / DV
Although there is a case such as D, at present, there is no case having the shape of the central holding portion 5 as shown in the storage case 1 having the above-mentioned structure, and therefore, it is about half of the conventional case of 5.2 mm. No such case of moderate thickness exists. Therefore, the case 50 of this type can be slimmed down 50% in a practical manner by the storage case 1 having the above-mentioned structure. In addition, practically, if it is 6 mm or less, a sufficient effect can be obtained as a thin case. According to the present invention, the thickness of the case 1 can be reduced to 5 mm or less.

The holding plate 2 and the cover body 3 are provided with a contact portion 45 (see FIG. 1) which abuts on each other when the cover body 3 is opened by 180 ° to maintain the open state. The contact portion 45 is formed in a shape that enables relative rotation between the holding plate 2 and the cover body 3 when a force in the opening direction is further applied from the opened state. More specifically, the contact portion 45 is composed of a hinge-connecting side edge of the cover body 3 and a side rib 21 of the hinge-connecting side edge of the holding plate 3, and both end edges can contact each other. It has been.

The peripheral wall 38 provided at the upper and lower edges of the cover body 3 is provided with a label locking claw 46 projecting inward. Labels and lyric cards are locked to the locking claws 46. As shown in FIG. 27, the cover body 3 is provided with a communication hole 47 penetrating in the thickness direction communicating with the locking claw 46. The locking claw 47 is attached to the peripheral wall 22 of the holding plate 2.
Is provided at a position corresponding to the second step portion 27. However, the dust entering from the communication hole 47 is prevented from entering by the peripheral wall 22.

In the storage case 1 having such a configuration,
The usage status will be described. First, the recording medium disk 10
To store 0, the cover body 3 is opened, and as shown in FIG. 8, the disc 100 is placed on the upper surface of the projection 13 of the holding portion 5, and the center hole 101 is aligned. At this time, since the projections 13 provided on the outer peripheral portion of the enlarged portion 12 become an obstacle, the disc 100 does not fit into the holding portion 5 as it is. However, simply pressing the disc 100 lightly allows the protrusion 13 to be pushed radially inward on the inner surface of the center hole 101 of the disc 100 as shown in FIG. Then, the central hole 101 passes through the projection 13 and the disk 100 is securely fitted into the rising portion 11 and the enlarged portion 12 as shown in FIGS. At the time of this fitting, a clicking sound is emitted, so that the fitting state can be confirmed.

When a force is applied to the disk 100 in the disengagement direction in this fitted state, the upper surface of the disk 100 comes into contact with the projection 13 and acts to increase the diameter of the enlarged portion 12, so that the disk 100 comes off accidentally. I will not do it. Then, the cover body 3 is closed. At this time, the engagement recess 28 and the projection 40 are engaged, and the closed state is maintained. Also, when the cover 3 is closed, there is only a gap between the upper surface of the disk 100 and the inner surface of the cover 3 that is less than the thickness of the disk 100, so the disk 100 is accidentally dropped from the holder 5 in the case 1. There is no danger.

The case 1 containing the disk 100 is
It is stored in a storage rack or the like. The case from the storage rack
When the case 1 is taken out, as shown in FIGS. 25 and 26, the case 1 can be easily taken out by putting the finger on the finger hook 44 and pulling out the case 1. On the other hand, to remove the disc 100 from the case 1, the cover 3 is opened. At the time of this opening operation, as shown in FIG. 26, if the user puts a finger on the finger locking portion 30 and further holds the knurl 39 to open the cover body 3, the opening operation becomes easy.

At this time, the positioning projections 41 provided on the peripheral wall 38 of the cover body 3 make the engagement between the engagement recesses 28 and the projections 40 left and right uniform, so that the opening operation is easy. Become. Then, open the cover 3 by 180 °,
3 and the holding plate 2 are in contact with each other by a contact portion 45 to maintain an open state of 180 °. At this time, even if an unexpected external force acts in the opening direction, the contact portion 45 gets over the contact state and allows the relative rotation between the cover body 3 and the holding plate 2, so that the hinge portion 2a, 3a does not break.

Next, after the cover 3 is opened, the pushing portion 14 of the holding portion 5 is pushed in as shown in FIG. Then, as shown by a two-dot chain line in FIG. 5, a reaction force is applied to the projection 13 by abutting on the inner surface of the central hole 101 of the disk 100, and the enlarged portion 12 is moved radially inward by the reaction force. This causes a diameter reduction effect. Accordingly, the holding portion 5 is reduced in diameter as a whole, and the protrusion 13
At the center hole 101. At this time, since a clicking sound is generated, the release of the fitting can be confirmed. After the projection 13 moves to the lower side of the center hole 101 of the disc 100, if the pushing operation of the pushing section 14 is stopped, the diameter of the enlarged section 12 is enlarged as shown in FIG. The disk 100 is supported on the upper surface, and the upward movement of the enlarged part 12 and the base 10 restores the
The disk 100 is lifted by the projection 13.

Therefore, the disk 100 may be gripped and taken out. That is, the disc 100 can be taken out only by a one-touch pushing operation of the pushing portion 14. Conventionally, the disk 100 cannot be easily removed by pushing the case on the desk and pushing the center holding mechanism because the elastic deformation allowance of the center holding mechanism was small. Therefore, conventionally, in a state where the case is suspended in the air, the center holding mechanism is pushed and operated to be largely deformed and taken out. However, in the present invention, the elastic deformation allowance of the base portion 10 and the enlarged portion 12 is large even if the pushing portion 14 is pushed while the holding plate 2 is placed on the upper surface of a flat desk. Since the moving amount is large, it can be taken out very easily.

In FIG. 28, the holding plate 2 is formed separately from a pair of cover members 50 and 51 which are swingably opened and closed with each other. It is structured to be loaded like an insole. This holding plate
The structure of the second holding section 5 is the same as that of the first embodiment. FIGS. 29 to 38 show various modifications of the holder 5, which can be replaced as the holder 5 of the above embodiment. That is, the one shown in FIG. 29 has two projections 13 and the like, and a base 10 is provided on the inner peripheral surface of the hole 9 of the holding plate 2 at a position equally divided in the circumferential direction. A semi-circular enlarged portion 12 is extended through a rising portion 13 at the extended portion.
A protrusion 13 is provided on an outer peripheral portion of an end portion of the thirteen, and a pushing portion 15 is protruded from an inner peripheral portion.

The two projections 13 are close to the rising portion 13. In this embodiment, no dust-proofing piece is provided. 30 is the same as that shown in FIG. 29 except that the dust-proofing piece 16 is provided in the hole 9 of the holding plate 2. In FIG. 31, the extension length of the enlarged portion 12 in the circumferential direction is reduced to about half of that in FIG. The one shown in FIG. 32 is one in which the dustproof piece 16 is enlarged and the space of the hole 9 is made as small as possible.
Others are the same as FIG.

In FIG. 33, the number of the projections 13 and the like is four, and in this case, no dustproof piece is provided. The one shown in FIG. 34 is provided with a dust-proofing piece 16, and the other is the same as FIG. The one shown in FIG. 35 has five protrusions 13 and the like, and in this case,
